    摘要: The object is to eliminate the difference in offset of work rolls at the upper and lower and left and right of the rolling mill occurring in the kiss roll state of the zero point adjustment work before rolling or during rolling and eliminate the problem of warping of the flat products or meander or camber due to the thrust force acting between the work rolls and backup rolls.
    For this, there are provided a rolling mill for flat products having a pair of upper and lower work rolls driven by electric motors, a pair of upper and lower backup rolls contacting the work rolls and supporting the rolling reaction force applied to the work rolls, and devices for applying substantially horizontal direction external forces to the upper and lower work rolls, the rolling mill for flat products characterized in that a direction of horizontal direction external forces applied to the work rolls is the same direction as the horizontal direction force component of the rolling reaction force applied to the work rolls due to the rolling direction offset and in that the horizontal direction external forces applied to the work rolls are supported by rolling mill housing project blocks or work roll chock support members, and a rolling method for flat products using the same.

    摘要: The invention relates to a multiple-roll rolling mill for strip material, comprising working rolls (1,2) which are supported on support rollers (6, 7, 8, 9-16b) through optional intermediate rolls (4,5). Said support rollers are rotationally mounted together on a support axle (17,18,19,20), respectively, this support axle being divided into at least three longitudinal sections (L1,L2,L3). The inventive rolling mill also comprises at least one actuating device which is allocated to at least one of the support axles (18) and comprises actuator drives (35,36,37), each of which is allocated to one of the longitudinal sections (L1, L2, L3) of the support axle (18), respectively and subjects the corresponding longitudinal section (L1,L2,L3) to a transversal force in relation to the longitudinal direction of the support axis (18), through a group (G1,G2,G3) of actuating mechanisms (24,25,26;27,28;29,30,31) which are intercoupled by a coupling member (32,33,34) in relation to their movement relative to the support axle (18), in order to correct the roll gap (3) between the working rolls (1,2).

    摘要: The invention relates to a roll stand, especially a duo or quarto roll stand, comprising bending and balancing devices (7) for axially displaceable rollers (4, 5). A fixed guide block (6) is secured on both sides in the window (1) of each roller stand (2) on the same level as the roller inserts (3). The force of the bending cylinders (8) is transmitted to the roller inserts (3) which are guided in the direction of the axis in a vertically displaceable manner. The length of the bending cylinders (8) on the upper and lower piston end is respectively greater than the width thereof and the longitudinal axis of the bending cylinders extends in the direction of axial displacement of the rollers (4,5).
